JULIUS ll. GARSON, OF DENVER, COLORADO.

PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 632,257, dated September 5, 1899.

Application filed March 2 2, l 8 9 8.

To aJ/Z whom it may concern:

Be it known that I, JULIUs H. GARSON, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Pipe-WVrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a pipe-wrench containing cogged wheels which may be clamped upon a pipe by means of a rod in the handle of said wrench, which acts as the thumb -screw does on the ordinary Wrenches now in common use. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 is a sectional view of the pipewrench, showing the entire device. Fig. 2 is a view of a vertical section of the same. Fig. 3 is a view of die, socket, and wrench as stock. Fig. 4 is a view of a vertical section of the same as Fig. 3. Fig. 5 is an interior view of the lower section of the stock. Fig. 6 is a view of a cross-section of the die. Fig. 7 is a view of die, socket, and bushing.

Similar figures refer to similar throughout the several views.

In Plate 1, 5 is the outside shell or solid part of the wrench in which the mechanical parts are contained or to which they are attached.

5 is a portion of the shell extending well upon the handle 6 to give additional strength to the whole device.

5 5 are rivet or screw holes in the shell 5 to receive rivets or screws to be used in fastening and holding the two equal parts of the wrench together.

"6 is the handle of the wrench, containing a cavity to receive the rod 7, around which the handle 6 is intended to revolve. The rod 7 has a thread thereon, and the cavity in the handle 6 also has a thread to receive the rod 7, and the handle 6 is loose around the rod 7, but secured to the shell 5 by a shoulder or other suitable means at the lower end of the handle 6, so that by turning the handle 6 the rod 7 will be drawn into or extended out of the handle 6, thereby contracting or expanding the space between the clamp-wheels 12, 13, 12, and 9.

T is a pin passing through the rod 7 and parts Serial No. 674,759. (No model.)

Thus the wrench will clamp upon any ordinary-sized pipe.

9 is the clamp-wheel, contained partially within the cavity in the lug 8. Said clampwheel 9 has a saw or other suitable edge in order that the pipe may be held firmly when the clamp-wheel 9, in connection with the clamp-wheels 12, 13, and 12, similarly constructed, is brought in contact with the pipe by means of the revolving handle 6, the thread therein, and the rod 7, with the thread thereon.

10 is a pivot upon which the clamp-wheel 9 operates. The pivot 10 passes through the clamp-wheel 9 and also through the lug 8 to its outer edges and flush with the same.

12, 13, and 12 are clamp-wheels in the forward end of the wrench, which act in conjunction with the elamp wheel 9 in lug 8 upon the pipe when the wheel 9 is advanced against the pipe by means of the revolving handle 6, as before described. As the Wheel 9 is advanced, the pipe is forced against the clampwheels 12, 13, and 12 and the pipe is then firmly fixed in position by being pressed between the clamp-wheels 9, 12, 13, and 12.

12 and 12 are the clamp-wheels upon which the ratchets or dogs 16 and 17 in the shell 5 of the wrench operate; These clamp-wheels 12 and 12 are pivoted directly in the shell 5 by means of pins 14 and let and are of the same construction as the clamp wheel 9. They may be adjusted in the direction of their movement by means of the ratchets or dogs 16 and 17.

13 is a loose clamp-wheel constructed and pivoted in a like manner as the clamp-Wheels 12 and 12, but is not controlled by ratchets, as they are. This clamp-wheel is placedbetween clamp-wheels l2 and -12, but not in contact therewith.

14: 14 are screws or pivots used to secure the clamp-wheels 12, 13, and 12 in position within the shell 5.

19 and 19 are the pins upon which the pawls 16 and 17 are pivoted to the shell 5.

2O 20 are the springs which hold the pawls 16 and 17 in position.

21 21 are pins which keep the springs 20 2O bent or sprung.

22 is a plate used to cover the opening in shell 5. This plate is riveted to the shell 5 or solid part of the wrench by the rivets 5 25 in Fig. 3 is the die in the casing 26 when all the clamp-wheels of the wrench are brought in contact with the same.

26 is the outer casing of the die 25, having a saw edge or cogs acting in the clamp-wheels 9, 12, 13, and 12.

26 is the outer casing around the pipesocket, as shown in Fig. 7.

26 is the lug held in place in die 25 by screws 31.

27 is the bushing, with screw thereon, to act in conjunction with the thread in the pipesocket 26.

28 is the set-screw to hold the bushing in Y place upon the pipe.

30 is the lug-plate to hold the die in place in the socket of casing26.

31 is the screw which holds the lug-plate 30 in the casing 26 to prevent the die 25 from falling out.

Having thus fully explained my invention in such a manner that those versed in the art to which it belongs may fully understand its operation, what I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the frame, a pipewrench with a series of clamp-wheels, one or more, of which is pivoted to a lug that is attached to a rod that screws into a revolving handle; two of the said clamp-wheels of the series being regulated in the direction of their movement, or fixedby double pawls which are attached or pivoted to the shell of the Wrench; whereby the wrench is adjusted to fit various sized pipes substantially as described.
